Passing information from Applet to IE on the client

Hi everybody,
Does anybody know if it is possible to pass HTML formatted string (or any string for that matter) to the IE on the client without forcing browser to go back to server ?
The situation is the following - Applet application has all information it needs to form an HTML page to be presented in the separate Window by the Browser. At this point it sends it back to the server and then calls Browser with the appropriate URL. It obviously clumsy. I am looking for a way to pass it directly on the client side. It is OK if some permissions should be granted to the Applet.
Thanks in advance.

Your JavaScirpt can communicate with your applet. Provide some methods on your applet that the JavaScript can call to gather all information, then your JavaScript can place this in an html window.
Make sure you ID your applet or NAME your applet ie ID = "myApplet". The JavaScript can then access this object as document.myApplet.callSomeMethodOnThisApplet().

Use JSObject:
html file:

import netscape.javascript.*;
public class someApplet extends java.applet.Applet {
    JSObject win;
    public void init() {
         try{
             win = JSObject.getWindow(this);
// you need win.eval("window.close();"); // to close the window. if the current window is not a popup
// opened by a parent with window.open than the user will get a waring, your next question probably will
// be "can I stop this warning" and the answer is simple: NO
             JSObject textBoxLabel = (JSObject) win.eval("document.getElementById('lblOutputText')");

Passing information from external asp file and getting it in the portal

Hi,
I think that the answer for my question is simple but I'm not sure how it is done.
I would like to pass information from asp page(microsoft server pages) to the portal and extract the information in the portal
I know how to how to pass the the information as POST or GET method
but how do I extract the infomation within an iView ?
and what is the portal URL I need to call from the asp page ? a page URL or an iView URL ?
Thanks
Y.R

Hi,
In order to use an ASP application in the portal u have to first create a system. In the System Definition Properties, give the url of your ASP page in the Name of server field and the name of the ASP page in the URI field.
For more clear understanding, please go through the following document

How can I pass information from one portlet to another?

First, some background...
I am using Portal 5.0.2 and developing portlets using JSP/Java on a remote server.
I need to pass information from a portlet on pageA to another portlet on pageB, but I can't do it using the traditional methods, such as query string, session, cookies, etc. due to either portal framework limitations or because of functional constraints (basically, a user will not necessarily be logged in to the portal, but he can view anything available to the GUEST user). Here are the different ways I've considered using to save state and their limitations:
Query string: can't use this because portlets on remote servers don't have access to it
Cookies: if user disables cookies, code will not function properly
Session variables: limited to one user's connection with one portlet (i.e., can't access a session variable set in portletA from portletB)
Application variables: because the user may not be logged in, I have no way of uniquely naming variables, which is a necessity in order to maintain state for EACH user
User Settings: again, the user may not be logged in, so I can't use these
PCC: can't access client-side variables because server-side JSP executes first
Are my assumptions above correct? Has anyone had any success using one of these methods given the same constraints, or does anyone have an alternative solution? I'd certainly appreciate any help anyone could provide.
Thanks,
Jose

One possibility would be to use a Login PEI to set a unique UserInfo Name/Value for the user. I think in 5.0 each guest session is unique, so would have unique UserInfo. Then you could pass this value to your portlet (by specifying it in the web service) and use it as a key into a Application-scoped hashmap where you store your info. In other words, your Application variables option, but you have a way of uniquely naming your variables via PEI-set UserInfo.

Passing information from an iView to SAP - ESS Related

Hi,
How do you pass information from an iView to SAP?
For example, in my task the User will log into ESS.
Then they will click on the iView link and be prompted with a dialog for their service number (how is that done)?
Now, on SAP's side (backend), I need to take that service number and their user id and pass it to the transaction.
For the service number, I will have to add leading zero's.
How is this done?
What is the ESS cookbook and does anyone have it?
Thanks,
John

Thank you for the response - it gives me a better idea of how this system works.
But how would you modify the information that is being passed? Would it be passed to a structure, which can be accessed from within SAP? For example, the medical service number would be entered as 15. It would be stored and then my program would extract that number, add leading zero's and call the relevant transaction.
Please help.

Passing information from JClient to View Object

What would be best way to pass information from JClient to View Object. I would like to implement security system, where view object would take information about what specific users can do (not oracle users, I would like to have one user to connect to database only) from an oracle table or stored procedure. Now I need to pass information about user: user name, IP, application etc. to View Object. I have two ideas for possible solution:
a) dynamic attributes
b) exporting methods (with custom interface)
Any suggestions ?

Passing Information From Socket to GUI

Hi, I'm making a chat client, but I'm having trouble passing information from server's input stream to my GUI. I made two threads, one for sending and one for receiving, and I start them both when I click "connect" after I log in to the server. So what happens is I run my program, the frame appears as I want it to, and then I click connect, and after a little wait the button "unclicks" (or w/e) and nothing happens. I don't know why I am not receiving the messages from the server. If I make the program "GUI-less" it works, I can both send and receive messages via the console. But in the GUI, where I am sending/receiving via my two TextAreas, it doesn't work. Here's my code:
(I apologize ahead of time for posting so much code in a thread, I tried to cut it down as best as I could.)
BotWindow class (GUI) - Action Listeners
public void createProps() {
        outText.setLineWrap(true); //Text Areas
        outText.setForeground(Color.white);
        outText.setBackground(Color.blue);
        outText.setEditable(false);
        inText.setLineWrap(true);
        inText.setForeground(Color.white);

                out.write(m);

                System.out.println(e);
            String blank = "";
            bw.inText.setText(blank);
            sr.src = null;
class Receive extends Thread {

    BotWindow bw;
    public Receive(InputStream inputIn) {
        in = inputIn;
        bw = new BotWindow();
    public void run() {
        while(true) { //thinking of doing while(sr.src != bw.submit)
            try {
                bw.outText.setText(bw.outText.getText() + (char)in.read());
            catch(IOException e) {
                System.out.println(e);
}So, to repeat my question, why isn't my GUI receiving the data being passed to it from the BattleNet socket? Also, am I taking the right approach on separating the send and receive methods and is my threading correct?

Just Look at this code...
while(true) { //thinking of doing while(sr.src != bw.submit)
try {
bw.outText.setText(bw.outText.getText() + (char)in.read());
catch(IOException e) {
System.out.println(e);
The problematic area is this code itself.
Try to read text Line by Line basis. You can do this by using readLine() rather than read().
The modified code should be like this:
while(true) { //thinking of doing while(sr.src != bw.submit)
try {
String TextRead=in.readLine();
String Prev_text=bw.outText.getText();
String new_Text=Prev_text + new_Text;
bw.outText.setText(new_Text);
catch(IOException e) {
System.out.println(e);
This would make the code easy to read and modify.
I have faced these kindaa problems during my JAVA project coding. However they have been solved by using a much simpler approach like the one I have used. Although they do the same thing, but anyhow it provides a better result for reasons quite unknown to me!!!

}So, to repeat my questions, SendAndReceive class, but I'm not sure if this is the right approach.why isn't my TextArea (BotWindow.outText) not receiving and setting it's text to the information from the server? Is my threading correct? Also, with the way I set up the threads, will the Send function be able to send in the midst of the receive function? I tried to set it up so that it could by implementing ActionListener in my SendAndReceive class, but I am not sure if this is the correct approach.
P.S. The reason I put this in Swing is because it works without a GUI/Swing components! If it will help, I will post the GUI-less program I made that works.

i was transferring my information from my old iphone to the new one, and i forgot that i had some pictures in the new one. i did the restoring information and the pictures in new one are gone. how can i get them back???? please

Only way to get it back is to restore your phone from a backup, if those pics were included in that backup.
But most likely those pics are gone.
What you should've done was import http://support.apple.com/kb/HT4083 the pics to your computer and after you restored from your old backup, you could sync those new pics to your phone via itunes.

Passing variables from php to flash and the opposite

Hi guys, im trying weeks now to solve this problem but nothing yet
If someone could just tell me how to pass variables from flash to php and the opposite i would be thankful!!! Please help!

I have recently had to learn this, so this may not be the best way but it worked for me
I suggest looking at the code below stripping out everything you don't need (e.g. the databse stuff) and just get a simple string going back and forward
have a go and post any problems here and I'll try and help
in flash i have
private function getBalanceAndXP():void
          var request:URLRequest = new URLRequest("utils.php");

}And yes there is another problem. I can compile and run the program in a C:\folder but when i open the document in a project workspace, i cant compile the above code. Can any one please offer me assistance?
Thanks a million.

To NanookOITheNorth:
Could you provide some more relevent information
about what the other program is and how data should
be transferred to it? API? Socket? File?was wanted to use the "return task" thing. Issit possible to use that?
To annie79:
my next program is supposed to retrive the events in the "task" field and display it in a applet. After retriving the tasks i will be getting the dates to produce the gantt chart. uses the jfree lib functions.

Pass byte[] from applet to servlet

I have an application that allows users to copy an image from the system clipboard into a frame. What I would like to be able to do, is save that image into a database (db2 on as/400). In order to do that, I try to send the image, which I turned into a byte[] in order to easily insert into the database, from the applet to the servlet using streams (no actual file io), but the image always comes up null when I pass it to the servlet. What am I doing wrong? The image gets copied and drawn from the clipboard just fine, but I can't send it to the servlet. I only included the part of the servlet that tries to retreive the byte array. I know the applet code is a little long, but I figured it might be of interest to someone. Please help!
Here's the code for the applet:

D,
I read your code. I believe you are trying to send the byte array with the wrong outputStream.write method. For a byte[] I have successfully used the form, servletOut.write(byteArray, 0, byteArray.length). You have to tell the receiver how much data will be sent to it so it knows when to stop read in the data.
Example:
_url = new java.net.URL(serverURL);
//Attempt to connect to the host
java.net.URLConnection connection = _url.openConnection();
// Initialize the connection
connection.setUseCaches(false);
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setRequestProperty("Content-type", "application/octet-stream");
BufferedInputStream fileInputStream = new BufferedInputStream(fIS);
int nBytesAvailable = fileInputStream.available();
byte byteArray[] = new byte[nBytesAvailable];
fileInputStream.read(byteArray, 0, nBytesAvailable);
fileInputStream.close();
fIS.close();
// send data to servlet, get outstream, write data, flush, close.
DataOutputStream outStream = new DataOutputStream(connection.getOutputStream());
outStream.write(byteArray, 0, nBytesAvailable);
outStream.flush();
outStream.close();

Passing values from applet using POST method to PHP page

Hello there ;)
I realy need a help here.. I`ve been working all day on sending mail from applet. I didn`t succeed bcs of the security restrictions.
So I decided just to pass arguments into PHP page, which process them and send e-mail to me.
So here is the problem.. I need to send String variables througth POST into my php page. Now I`m using GET method, but I need more than 4000 characters.
My actual solution is:
URL url = new URL("http://127.0.0.1/index.php?name=" + name + "&message=" + message);
this.getAppletContext().showDocument(url,"_self");I really need to rewrite it into POST. Would you be so kind and write few lines example [applet + php code]? I`ve already searched, googled, etc.. Pls don`t copy links to other forums here, probably I`ve read it.
Thanx in advance to all :)

hi!
i`ve got some news about my applet.. so take this applet code:
public class Apletik extends JApplet {
    public void init() { }
    public void start()
    try
      String aLine; // only if reading response
      String parametersAsString = "msg=ahoj&to=world";
      byte[] parameterAsBytes = parametersAsString.getBytes();
      // send parameters to server
      URL url = this.getCodeBase();
      url = new URL(url + "spracuj.php");
      URLConnection con = url.openConnection();
      con.setDoOutput(true);
      con.setDoInput(true); // only if reading response
      con.setUseCaches(false);
      con.setRequestProperty("Content=length", String.valueOf(parameterAsBytes.length));
      OutputStream oStream = con.getOutputStream();
      oStream.write(parameterAsBytes);
      oStream.flush();
      String line="";
      BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
      while ((aLine = in.readLine()) != null)
       JOptionPane.showMessageDialog(null, aLine);
       if(aLine.equals("")) break;
      in.close();
      oStream.close();
    catch (Exception ex)
      JOptionPane.showMessageDialog(null, ex.toString());
}here is code of spracuj.php which is on server:
<?php
if(isset($_POST['msg']))
    echo('hurray!');
?>it has only 1 problem.. when i test it on my localhost, everything seems to be all right. but when i post it to my server, i got IOException HTTP 400 error code :( where is the problem? please help me, i`m so close :D thanx

Passing Information from UCCX call variables through trunk SIP to Astersik

Hi All,
We need to pass some informations from our UCCX 8.5SU3/CUCM 8.6.2a to our Asterisk Server.
This two PBX are connected by a trunk sip.
Is it possible to do it?I've read about sip header,but i've never work on it.
Is it possible with a javascript?
Could you please help us?
Thanks
Stefano

No. CCX uses JTAPI (CTI/QBE) to integrate with CUCM, not SIP. As such there is no mechanism for it to manipulate or add extra SIP headers. You would need to use one of the native scripting options (e.g. ODBC, HTTP GET/POST, SMTP) or write a custom Java class that can interface natively with the other application. Examples of this exist such as the excellent documents on SFTP, CIFS, and LDAP.
Please remember to rate helpful responses and identify helpful or correct answers.
